This brings us to the book's conclusion. Hopefully, you have enjoyed the ride. To reiterate, perhaps, the most important tip in this book, always make sure that you verify the source of the performance bottleneck via benchmarking before making a single change. The last thing we want to waste time on is chasing ghosts in the codebase, when 5 minutes of profiler testing can save us an entire day of work. In a lot of cases, the solution requires a cost-benefit analysis to determine whether we're not sacrificing too much in any other area at the risk of adding further bottlenecks. Make sure that you have a reasonable understanding of the root cause of the bottleneck to avoid putting other performance metrics at risk. To also reiterate the second most important tip in this book, always profile and test after making changes to ensure that it had the intended effect...

Overview of this book
Unity is an awesome game development engine. Through its massive feature-set and ease-of-use, Unity helps put some of the best processing and rendering technology in the hands of hobbyists and professionals alike.
This book shows you how to make your games fly with the recent version of Unity 2017, and demonstrates that high performance does not need to be limited to games with the biggest teams and budgets.
Since nothing turns gamers away from a game faster than a poor user-experience, the book starts by explaining how to use the Unity Profiler to detect problems. You will learn how to use stopwatches, timers and logging methods to diagnose the problem. You will then explore techniques to improve performance through better programming practices.
Moving on, you will then learn about Unity’s built-in batching processes; when they can be used to improve performance, and their limitations. Next, you will import your art assets using minimal space, CPU and memory at runtime, and discover some underused features and approaches for managing asset data. You will also improve graphics, particle system and shader performance with a series of tips and tricks to make the most of GPU parallel processing.
You will then delve into the fundamental layers of the Unity3D engine to discuss some issues that may be difficult to understand without a strong knowledge of its inner-workings. The book also introduces you to the critical performance problems for VR projects and how to tackle them.
By the end of the book, you will have learned to improve the development workflow by properly organizing assets and ways to instantiate assets as quickly and waste-free as possible via object pooling.
